We analyze the effect of carrier confinement on the charge-transport properties of organic field-effect transistors. Confinement is achieved experimentally by the use of semiconductors of which the active layer is only one molecule thick. The two-dimensional confinement of charge carriers provides access to a previously unexplored charge-transport regime and is reflected by a reduced temperature dependence of the transfer curves of organic monolayer transistors.
我们分析了载流子限制对有机场效应晶体管电荷输运性质的影响。通过使用活性层只有一个分子厚的半导体，实验上实现了限制。电荷载流子的二维限制提供了一个以前未探索过的电荷输运状态，这反映在有机单层晶体管的转移曲线的温度依赖性降低上。
